Low Level Light Therapy

Low Level Light Therapy (LLLT) is a therapeutic technique that uses light as an intervention to produce physiological effects. It typically involves the use of low-level lasers or LEDs, which emit monochromatic red and near-infrared light. The light is applied directly to affected areas of the body for various periods of time depending on the condition being treated. LLLT has been shown to reduce inflammation, pain, edema, and tissue damage while promoting healing and regeneration of damaged cells and tissues. It has also been used successfully to treat skin conditions such as wrinkles, acne scars, eczema, rosacea, psoriasis and hair loss. Some LLLT's can penetrate deeper for bone stimulation and through the skull for brain stimulation.

Benefits and Risks of Low Level Light Therapy

Overview of Benefits and Risks Associated with LLLT. The primary benefits associated with LLLT are that it is non-invasive, painless, and relatively inexpensive when compared to more traditional treatments. It also does not require strong medications or topical creams and can be used as an adjunct treatment in conjunction with other therapies.

LLLT is considered low-risk since there are no known long-term negative side effects. However, some patients may experience a slight warmth or tingling sensation during treatment, which can be resolved by adjusting the distance or turning off the light.

Is Low Level Light Therapy Legitimate?

Yes, Low Level Laser Therapy (LLLT) is a legitimate therapeutic technique that has been studied extensively and used safely for many years. Its safety and effectiveness have been documented in numerous clinical trials, with research suggesting it may be beneficial for treating a variety of conditions including skin damage, pain relief, inflammation reduction, and wound healing. While LLLT is not appropriate for all medical conditions, it can provide significant benefits to those who suffer from certain types of chronic pain or skin conditions. Additionally, its non-invasive nature makes it an attractive option for those seeking alternative treatments. As always, it’s important to consult with your healthcare professional before beginning any treatment regimen.

What are other names for Low Level Light Therapy?

Low Level Light Therapy is also known as Phototherapy, Low-Level Laser Therapy (LLLT), Cold Laser Therapy, Soft Laser Therapy, Biostimulation, low energy laser therapy, and photobiomodulation. It is important to note that there are several different types of phototherapy, including intense pulsed light (IPL) therapy and laser resurfacing procedures which are more invasive than LLLT and should not be confused with the same type of treatment. Additionally, some clinics may refer to it as “laser acupuncture” or “low level laser stimulation”. It may seem confusing but it is using lights to stimulate your cellular activity.

What are the healing frequencies for Low Level Light Therapy?

The exact healing frequencies for Low Level Light Therapy (LLLT) will depend on the condition being treated. Generally speaking, the light used in LLLT is monochromatic and usually falls within the red and infrared spectral range of 633-950 nm. Visible light ranges from 450 to 750 nm range which is the blue and red light spectrum. The frequency can also be adjusted based on the area of treatment and the size of the affected area. For instance, deeper tissue damage may require more intense light frequencies than superficial wounds or on a patient's skin.

The 633 nm red light can help with circulation, collagen production, wrinkle reduction, and skin rejuvenation.

The 660 nm light is used for skin treatments such as acne.

The 810 nm wavelength is used for various types of pain, inflammation, nerve damage, pain management, and wound healing.

The 850 nm light can penetrate deeper through the skull and benefit neurons with all the benefits of the other frequencies including pain management, tissue healing, pain reduction, and more. Penetrating the skull is important as we see significant differences with our clients especially with concussions, traumatic brain injuries, strokes, and other types of physical head injuries.

What is a Light Emitting Diode?

Light Emitting Diodes (LEDs) are small electronic devices that convert electricity into light. They come in a variety of colors, sizes, and shapes. LEDs are commonly used for lighting but can also be used as part of Low Level Light Therapy. LEDs emit monochromatic light at specific frequencies (therapeutic range from of 630-950 nm) that can penetrate deep into the skin and stimulate cell repair and regeneration for significant improvement.

What are the risks associated with Low Level Light Therapy?

Although LLLT is considered low-risk due to its non-invasive nature, there may be some minor adverse effects associated with treatment. These can include mild irritation or discomfort in the area of application as well as temporary redness or swelling as inflammation is reduced.

Overall, Low Level Light Therapy (LLLT) can provide numerous benefits when used correctly. With its wide range of healing frequencies, this type of therapy can be applied in a variety of ways for various conditions and injuries while providing minimal risks and discomfort. When combined with other therapeutic techniques, LLLT is a great treatment for accelerated healing.

Evidence Supporting Low Level Laser Therapy as an Effective Treatment Option.

There is a growing body of evidence that suggests Low Level Laser Therapy (LLLT) can be an effective care for a variety of medical conditions. Studies have shown that light treatment can reduce inflammation, pain, edema, and tissue damage while promoting healing and regeneration of damaged cells and tissues.

Research also suggests it is beneficial in treating skin conditions such as wrinkles, acne scars, eczema, rosacea, psoriasis and hair loss. Additionally, there is some data to suggest LLLT may provide relief from certain types of chronic pain such as osteoarthritis pain or neuropathy. Anti inflammatory effects are also noticed with the use of a low level laser light during a treatment session.

While we would all like to see more randomized controlled trials there is a lot of research that has been completed to date. Low Level Laser therapy is a powerful tool and continues to show promise as a safe and effective treatment option. For more research please visit www.pubmed.org and search low level light therapy, low level laser therapy, laser therapy, level light therapy, low intensity laser therapy, light therapy, photobiomodulation, laser biostimulation, and red light therapy.
